Is DL533N XL is compatible with an Arduino setup?
DL533N Series of devices do not have physically extracted UART pins, so the only available communication option is the USB. Therefore, for implementation on Arduino, you need to use a USB to serial converter.
If you are not bound to Libnfc, I suggest using our µFR XL NFC Reader which supports UART.
µFR XL is based on our API and Communication protocol, and we also provide an Arduino library for it.
